After a shaky and out-of-key performance at the Grammys earlier in the month, after which Adele said she cried all day, she closed the show with an accomplished rendition of "When We Were Young", a song from "25", having changed into a star-spangled glittery gown before her performance.

Adele also said she wanted to "publicly support" American pop star Kesha, who claims that her former music procuder, "Dr. Luke", raped and emotionally manipulated her. A judge ruled last week that Kesha could not be released from her six-album recording contract with Sony Music.
